    Ok, a very technical question.
    I always believed that plasmas showed an entire image at the same time. However, I just learned that in fact, every (sub)pixel is addressed in sequence and that thus at any time only 1 (sub)pixel of the entire screen is excited. As a result, plasma is just as susceptible to flicker as CRT is, and therefore you have things like 100Hz also in plasma (e.g. Panasonics latest models).
    I still have a next question: how is the brightness/intensity of each (sub)pixel controlled ? Is it by the magnitude of the voltage applied to the cell, or is it by the duration of the applied voltage ?
    (I already have an educated guess, which would also solve a different question I have, but I'll await the answers first).
